IVALTER S. FBAZIER, OF AURORA, ILLINOIS.

TWO WHEELED VEHICLE.

SPECIFICATION forming part of Letters Patent No. 299,12e, dated May 27, 1884. Application filed March 22, 1883. Renewed February 29, 1884. (No model.)

To all whom it may concern:

Be it known that I, \VALTER S. FRAZIER, residing at Aurora, in the county of Kane and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Road-Oarts or Sulkies, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a top or plan vietv; Figs. 2 and 3,side views; Figs. 4, 5, 6, 7, 8, and 9, details of the seat; Fig. 10, an axle with adjustable spindles; Fig. 11, one end of the axle with adjustable spindle; Figs. 12, 13, and 14, details of the axle adjustment; Fig. 15, details showing the improved construction of device for connecting parts with the axle; Figs. 16 to 20, inclusive, details showing the attachment of the seat-arms and foot-rest arms with the thills.

The object of this invention is to improve and perfect the construction of road-carts in their various details without materially changing the general character of the cart, as the general characteristics of the cart shown are the same as those of the carts heretofore patented to me; and the invention consists in the various improvements of the parts and combinations of parts hereinafter described and claimed as new.

In the drawings, A indicates the wheels; B, the axle; B, adjustable spindles; G, thills or shafts; D, seat arms or supports; E, foot-rest arms or supports; F, foot-rest; G, seat; H, seat-rail; I, step bar or shank; J, brace; K, a double clip for connecting the shafts with the axle; L, seat-box; M, adjusting-joint of the shafts; N, cross-bar of thills; O, whiffletree; a, removable seat board or bottom; I), projections for holding or securing it in place; 0, back springs attached to seat-board (I, back removable with the board a,- e, flanges on the seat-box L; f, ledges for supporting the seatbox Land seat-board a; g h t, frame of the seat; j 76, projections on the axle-bar B; Z, collar or enlargement on the spindle B; m, locking-screw on the inner end of the spindle B; n, locking serrations or teeth; 0 1), arms of the double clip K; q, under groove or recess in the step bar or shank I; r, an extension of the foot-rest arms E; s, safety-plate on the forward end of the seat-arm D; t, bearingplates 011 shafts 0; a, pivoted bolt; 1), projection on the shank I, fitting a corresponding notch, o, in the axle B; w, support for the seat-rail H; a, head of the support to; y, bolt of the thill-joint M; 2, serrations or teeth.

The wheels A are of ordinary construction, and for use with any of the improvements herein described. Thesha fts, axle, and seat may be ofthe ordinary construction, as I do not confine the use of any one of the several improvements herein described to any cart or sulky embracing all of the others. For some purposes the axle, shafts, and seat will have a special construction, as hereinafter described.

The spindles B of a sulky, as in other vehicles, are bent or inclined downward at their outer ends, in order to give the wheels their proper running position, so that in a cart, when the spindles are properly adjusted for a certain height of the front end of the shafts, a change of that position, either higher or lower, affects the position or dip of the wheels, and it also changes, to a greater orless extent, the position of the seat.

One of my improvements is for adjusting the proper position of the wheels to the height of the horses, and I accomplish this purpose by the arrangement shown at Fig. 10, in which the axle-tree or bearing is provided with proj ections j 76, which projections receive the spindles, as shown in a more enlarged form at Fig. 11that is, the spindles B pass through the projectionsj 7t, and at their inner ends they are provided with a screw-nut, m. The projection j is provided with teeth or radial serrations n, and the enlargement or collar Z of the spindle is provided with corresponding teeth or serrations. By this arrangement, when the height of the front end of the shafts is determined, the spindle B can be loosened and turned to give it the proper pitch and position for the wheel, when it is locked by screwing up the nut m, which causes the teeth or serrations to interlock and hold the spindle fast in theposition in which it has been placed. It will be readily understood that this adjustment is equally effective for the raising or lowering of the shafts. This arrangement, however, does not maintain the seat in its original the shafts are cut as shown at Fig. 1, one-half of each joint is attached to each part of a shaft, and the two parts are provided with teeth or radial serrations z and a locking-bolt, y, running through both sections. By the use of this arrangement the front ends of the shafts may be raised or lowered without disturbing the proper running position of thewheels and the adjustment of the seat in relation to the axle, and while both methods of adjusting the shafts with the axle may be used in the same cart it will readily be understood that one may be used without the other; but I prefer to use the two together.

The seat-arms D are pivoted to the shafts, as shown in the detail figures of Sheet 4, and rest upon springs connected with the shafts or with the cross-bar N in any convenient manner, as the method of giving the seat and footrest a suitable springsupport forms no part of this invention. The seat-arms D extend back to the seat, as shown, and, as shown at Figs. 5 and 7, they formthe ledges or support for the removable seat-bottom. and for the seatbox L, and the seat is formed by making a frame composed of the parts 9 h i, attachedto the arms D, and forming the ledges or supports f, leaving a space adapted for the reception of the seat-board a and the seat-box L.

The seat-board a is made removable, and is provided with spring-arms c and a back rail or support, (I, and it is provided with the projections b, which, when the seat-board is in place, pass under the front rail, g, and hold it down in such a manner that it does not move by resting against the back (1. This detachable seat-board can be used either with or without the box L, which box is usually made of tin or sheet-iron, provided with the flanges c, which rest upon the ledges f of the seat. Preferably this seat-box is made detachable, so that it may be taken out or applied, as desired.

In putting the parts together, the box L is first put in position, as shown in Fig. 8. The seat-board a is then placed over the box and in the same opening through the seat.

The back D of the board a may be the only back of the seat, as shown in Fig. 4; or it may be used in conjunction with the rail H, as shown in Fig. 3. This arrangement makes a strong and convenient seat of afew parts. The supportsEfor the footrest are connected with the ends of the arms D, substantially as shown, and they carry the foot-rest F. The space between the arms D and E may be wholly or partly paneled or boarded. These supports are attached to the rear ends of the arms in any suitable manner. At the front as to pass up between the end they are formed, as shown on Sheet 4, so arms and the shaft and form the plate r, by which they are attached to the top of the arm D. They are also provided with a hole, through which the bolt it passes. This bolt is supported by the hearings or plates 8 and t, as shown in Fig. 19, the plate 2, which is attached to the shaft, being provided with three bearings or openings, as shown, by the use of which the seat may be adjusted so as to change its position forward or back, and this is done without changing anything further than the bolt u from one position to another.

It has heretofore been difficult. to secure shafts to the top face of an axle in a firm manner, and also to so attach them that in use the shafts would not move along the length of the axle. I remedy these difficultiesby constructing a double clip, K, provided with prongs or arms 19 of a sufficient length to properly receive wooden shafts, and also provided with prongs or arms 0, which pass sufficiently below the axle to properly form the axle-clip, and I form the plate of the clip of the brace .I when there is no step applied; but in applying the step I form the shank I with a groove or recess, q, into which the end or plate part of the brace J fits, so that each strengthens the other; and by this arrangement I attach the shaft, the brace, and the step by one clip.

In order to prevent the working or use of the vehicle from causing the shaft to slip along the axle, I make a small notch therein under the clip, as at c, Fig. 15, and I apply to the shank I of the step a projection, 12, which fits into it, and thereby prevents any movement of the rear end of the shafts along or upon the axle. The projection '11, when the step, with its shank, is made of malleable cast-iron, is cast thereon. If the shank is made of wroughtiron, I punch it up from below. When the step is not used, the projection o is punched or otherwise formed on the plate of the brace J.

I also simplify and improve the means for attaching the support or supports 20 of the seat-rail H. I form them with a head, 00, through which there is a hole to fit the rail H, or one very slightly larger, so formed that it may be slipped onto the rail and brought to its proper position, and then hammered to lock it to the rail H. WVhen these supports w are made of malleable iron, they may be made to closely fit the arm H and put in position while hot, and allowed to shrink onto the rail and be locked thereto in that manner. Either way gives the seat a strong support and avoids the welding or riveting heretofore deemed necessary for attaching these supports to the backrail or lazy-back.

It will be evident that the parts r of the arms E may be a separate part of about the length shown at Fig. 17, to which the arm E may be bolted or otherwise attached. The bolt 10 may have one side of its head flattened,

as shown in Fig. 20, to prevent its turning around.

By the use of these several improvements the character, stability, and usefulness of the sulky or road-cart is very much improved, the cost of manufacture lessened, and many objections which have heretofore existed in this class of vehicles are removed.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

l. The seat G, composed of a frame, substantially as described,'with removable scat-board a, having the projections 12 and back d, substantially as specified.

2. The seat composed of the frame g h t, attached to the arms D, and thereby forming the ledges f, in combination with the removable seat-board a, substantially as specified.

3. The combination of the seat-frame, constructed substantially as described, with the removable seat-board a and the removable box L, both resting upon and supported by the arms D, substantially as set forth.

4:. The combination of the removable seatboard a, having, the spring-back c d, with a seat having a rail, H, substantially as set forth.

5. The extension or plate 7*, arm' D, and bolt u, in combination with the arm E, and plates 8 and t, and shaft 0, substantially as specified.

6. The axle B, having at each end two depending projections, j and k, the former serrated on their outer faces, in combination with the spindles B, passing through the depending projections, and having collars l, serrated on their inner faces, and nuts m, securing the spindles, substantially as described.

7. The step-shank I, having the groove or recess q. in combination with the axle B and the brace J, substantially as and for the purpose specified.
